Background technology

In general Western-style flushing just in the tool, the flushing water of supplying with from water-supply sources such as water pipes is stored temporarily in low level cistern etc. just has the wc flushing cistern, just have a flushing water in the wc flushing cistern and carry out Western-style flushing of just having a main body by being stored in this.This just has a wc flushing cistern and is arranged at and Western-stylely just has outside the main body, can be placed on Western-style rear portion of just having a main body, or be installed on the sidewall of washroom, and for excreta fully from Western-style just have discharge the main body, wc flushing cistern should have enough the flushing water of big volume once enter to Western-style just to have in the main body.But, in this general Western-style flushing just in the tool, need and just have a space that is provided with of wc flushing cistern.Therefore, in recent years, consider from effectively utilizing viewpoints such as space, continually develop at water-supply source and Western-style flushing switch valve (flow control valve) just is set between the tool, by opening just tool (Japanese patent laid-open 3-90723 communique, No. 2841537 communiques of special permission) of the Western-style flushing of no water tank that switch valve can directly supply with the flushing water of supplying with from water-supply source.

In the Western-style flushing of this no water tank just in the tool, the just tool flushing waterworks that carry out Western-style flushing of just having a main body by the flushing water of directly supplying with from water-supply source are located at Western-stylely just has on the main body, by being contained in opening of switch valve on the just tool flushing waterworks, flushing water is directly supplied with the Western-style main body of just having.Just tool washes waterworks, and switch valve has on valve bonnet as the water inlet of import with as the delivery port that exports, and the valve system that can regulate aperture between water inlet and the delivery port is arranged.Water inlet is connected with water-supply source, and flushing water is taken in the valve bonnet, and delivery port is just had a main body and is connected with Western-style, can just have flushing water a main body and discharges from valve bonnet is Western-style.In addition, as valve system, be provided with dividing plate between water inlet and delivery port, the operation of the electromagnetic valve that this dividing plate can be by open-and-shut action is out of shape.Therefore, these are just in the tool flushing waterworks, and the operation by electromagnetic valve makes the dividing plate distortion, can regulate the aperture that is communicated with of water inlet and delivery port with this.

In addition, the Western-style flushing of this no water tank just the switch valve of tool be by, stream use with the edge of conduit etc. in the edge that the set water flowing road, edge, top of Western-style bedpan of just having a main body is provided with the supply flushing water and the generation that is provided with on the bottom of bedpan forces the injection of the spray-hole supply flushing water of siphon effect to be formed with stream with injections such as conduits.And, switch valve carries out flushing water is fed to the edge with in the stream on one side, wash the edge water flowing operation of the internal face of bedpan by the flushing water that flows down from water flowing road, edge, carry out that on one side flushing water is fed to injection and spray flushing water at a high speed, produce the injection water flowing operation of forcing siphonic effect and the excreta that is excreted in the bedpan being discharged with stream and from the spray-hole of bedpan inside.This edge forms separate different paths with spraying with stream with stream.In the Western-style flushing of above-mentioned no water tank just in the tool, when switch valve transfers to when cutting out from the open mode of supplying with flushing water, the flushing water of water flowing road, edge or spray-hole produces negative pressure with stream and injection outside the upstream with stream at the edge with after the stop supplies, and the danger that causes counter-current of sewage will be arranged.Therefore, just in the tool, with stream with on spraying with stream the vacuum circuit breaker that is communicated in atmosphere is set respectively at the edge, in the Western-style flushing of this no water tank to prevent the adverse current of sewage.

And then, as the just pressure siphon of tool just in the tool of no water tank Western-style flushing, control with the feedwater time of stream with stream and injection by the current switching device shifter edge that staggers.The pressure siphon that has this current switching device shifter shown in Figure 122 is an example of tool 1 just.In this current switching device shifter, be connected with two the water service pipe Q of branch, R by constant flow rate valve L among the main feed water pipe P that is connected with water-supply source, on each the water service pipe Q of branch, R, switch valve M, N are set, and a side the water service pipe Q of branch is connected with water flowing road, edge 2, the opposing party's the water service pipe R of branch is connected with the spray-hole 5 of the bottom of bedpan 4.In this existing current switching device shifter, forcing siphon just during the flushing of tool 1, the switch valve M that only opens one of them at the beginning makes flushing water flow to water flowing road, edge 2 from the water service pipe Q of branch, carries out the flushing of bedpan 4.Then, close above-mentioned switch valve M, the switch valve N that opens the opposing party makes flushing water spray in discharge pipe 3 from spray-hole 5 via the water service pipe R of branch.Because discharge pipe 3 is filled water hastily, so promptly produce siphonage.Estimate flushing water to discharge and the period of siphonage end, close switch valve N and stop feedwater to the water service pipe R of branch of spray-hole 5 one sides, and open branch water service pipe Q to bedpan 4 in the additional flushing water of switch valve M once more, forcing siphon just to form water shutoff in the tool 1 from water flowing road, edge 2 one sides.

In addition, the flushing type that valve system arranged in valve bonnet just tool on valve bonnet, be formed into the mouth of a river, delivery port and access with in the switch valve.Access is communicated with water inlet and delivery port, and this access can come switch by valve system.This flushing type is the tool switch valve just, as mentioned above, if valve system is opened access, just then have a main body and discharge to Western-style via delivery port by water inlet from the flushing water of water-supply source, just becomes possibility with this Western-style flushing of just having a main body etc.And, if just Western-style end such as flushing of having a main body, then valve system is closed access, and the discharge of Western-style flushing water of just having a main body finishes.

And then usually, the wc flushing cistern of just having is provided with the manual handle that can shake, when the user shakes this manual handle by manual operation, then just has a valve of wc flushing cistern bottom because of the chain of manual handle traction lifts to be located at, and makes it to become open mode.Therefore, the interior flushing water of wc flushing cistern of just having supplies to the Western-style main body of just having, and washes the Western-style main body of just having.So, when by manual operation manual handle being shaken, because of overcoming the hydraulic pressure that acts on the valve manual handle is shaken, so this needs power to a certain degree, be not fine operation for quite weak old man of strength or heavy patient.Therefore, also developed in recent years the electro-motor that automatically drives manual handle is installed in and just had on the wc flushing cistern, and just tool flushing has been located at just tool of the Western-style flushing left on the Western-style toilet wall of just having a main body separately independently with button and manual handle.At just tool of this Western-style flushing, if just leave just tool flushing button on Western-style user's pressing operation toilet wall of having a main body after using up, then electrical motor driven and manual handle is shaken can be washed the Western-style main body of just having.In the case, because just tool flushing does not need so big power with the pressing operation of button, so can bring into play good operating characteristics.

In addition, in the Western-style flushing of above-mentioned no water tank just in the tool, just having main body when washing to Western-style, can according to the gutter that is connected with Western-style trap of just having main body for the underdrainage structure still on the ground discharge structure can correspondingly select the quantity delivered of flushing water.Therefore, come opening the time of gauge tap valve, the flushing water of suitable amount is provided, thereby can more effectively washes the Western-style main body of just having according to discharge structure.

Summary of the invention

{ the 1st invention }

But, at above-mentioned existing switch valve, adopting as valve system to be rich in flexual dividing plate, action response instability when dividing plate is out of shape for example is being used in Western-style flushing when just having, and the reliability of aspects such as its detergency is worrying.

Particularly, in this switch valve, the one side of this dividing plate is being born the pressure of the flushing water in the water inlet all the time.Therefore, opposite with the operation of the electromagnetic valve that reduces aperture during the hypertonia of the flushing water in water inlet in this switch valve, water inlet becomes big easily with the aperture that is communicated with of delivery port.Otherwise opposite with the operation of the electromagnetic valve that strengthens aperture during the hypotony of the flushing water in water inlet, water inlet diminishes easily with the aperture that is communicated with of delivery port.The change of the pressure of the flushing water in these water inlets produces along with employed environment of switch valve such as the high level of building or depth underground etc.Therefore, can think that this switch valve action response is difficult to stablize.

The 1st invention is in view of above-mentioned actual conditions, the switch valve that a kind of stabilizing that can realize action response is provided as the 1st problem to be solved.

The switch valve of the 1st invention is import and outlet to be arranged on the valve bonnet and have the switch valve of the valve system that can regulate aperture between this import and this outlet, it is characterized by, wherein

Above-mentioned valve system comprises that the peripheral operation by external manipulation mechanism can be provided with vertically slidably in above-mentioned valve bonnet, by along should axial side slip seat surface of being seated at this valve bonnet close being communicated with of this import and this outlet, by slide off along this axial opposite side this seat surface open the piston that is communicated with of this import and this outlet and this piston have from this import maybe the pressure that offsets of the interior pressure that this fluid and opposite side bore of this outlet offset the chamber.

In the switch valve of the 1st invention, if by the peripheral operation of external manipulation mechanism a piston side is vertically slided, then piston is seated at the seat surface of valve bonnet, being communicated with between closing import and exporting.Under this state, stop from the mobile of fluid of import.In addition, if by the peripheral operation of external manipulation mechanism piston opposite side is vertically slided, then piston leaves the seat surface of valve bonnet, being communicated with between opening import and exporting.Under this state, according to aperture, fluid flows in the valve bonnet from import, discharges from outlet.So, in the switch valve of the 1st invention, can regulate the aperture that is communicated with of import and outlet by the peripheral operation of external manipulation mechanism.

So because of the switch that is communicated with that is undertaken by piston between import and the outlet, so piston bears pressure because of the fluid in the import or export at its opposite side.At this moment, there is not the not therefore pressure of opposite side and of flexual piston to opening the side distortion.But, as long as be provided with the space of piston slip usefulness, this pressure to opposite side make the axis of the piston to sliding hindered.Therefore, in the switch valve of the 1st invention, this pressure to opposite side offsets in mechanism by the pressure payment, guarantees the endwisely slipping property of piston with this.Therefore, in the switch valve of the 1st invention, action response has been stablized, and can improve the reliability of the aspects such as detergency when being used for for example not having the Western-style flushing of water tank and just having.

In addition, in the switch valve of the 1st invention, open-closing velocity, open hastily-close so can eliminate the sort of that the dividing plate of existing switch valve causes because can at random set by the action of piston.Therefore, in the switch valve of the 1st invention,,, suppress noise etc. so can prevent the generation of water hammer even, also can prevent quick closedown because there is the fluid of big flow to flow through.

And then, in existing switch valve,,, be easy to generate the pressure loss so when fluid low pressure, be difficult to open fully because use dividing plate etc.This point for existing switch valve, if also can open fully when making fluid low pressure, reduces the pressure loss with this, then because be necessary to add large baffle, so this switch valve must maximize, make Western-style flushing just the installation of tool etc. be affected.In contrast, in the switch valve of the 1st invention, even because small-sized piston also can open fully when the fluid low pressure by its action, so be not easy to produce the pressure loss, and not necessarily maximize, can bring into play the just good installation of tool etc. of Western-style flushing.

As pressure payment mechanism, can adopt pressure payment chamber that forms by opposite side and a side that is communicated with piston at piston therewith the pressure path that offsets the chamber form.If like this, then the fluid that is present in a side of piston from import or export moves to pressure payment chamber via path, realizes the balance of fluid pressure of a side of fluid pressure that the pressure payment is indoor and piston, eliminates or reduce both pressure reduction.

Though path also can form on valve bonnet, preferably forms on piston.If though form path on valve bonnet, then because piston slides vertically, institute is so that path bending etc., it is complicated that path becomes, if form on piston, then can connect vertically path etc. is set, and can adopt simple path.In addition, if connect vertically path is set on piston, then the fluid that moves in path is not subjected to resistance when piston slides, and the sliding of piston improves.

Preferably the import of valve bonnet is opened in the side face side of piston, and the outlet of valve bonnet is opened in the end face side of an axial side of piston.If like this, then piston can not make opposite side bear pressure because of the fluid in the import, even make the fluid pressure in the import too high or too low because of the employed environment of switch valve is different, they can not make the sliding of piston change yet.

As external manipulation mechanism, can preferably adopt and be fixed in piston and outstanding by peripheral operation structure of piston such as magnetic force though also can adopt from valve bonnet, overcome the axle that load maintainer slides piston vertically.If like this, then because of the electromagnetic valve that there is no need to adopt existing switch valve such, so can reduce the manufacturing cost of switch valve.Particularly, when using a plurality of switch valve, carry out switch by each electromagnetic valve,, then can come each axle of switch, will reduce manufacturing cost effectively by each cam if adopt this axle though in existing switch valve, have to.

The 1st the invention switch valve in, can adopt as shown in Fig. 9 (A)～Fig. 9 (D) load maintainer with the axle relation.Here, can adopt the dipper crowding gear such as pushing spring of pushing piston and the haulage gears such as stiff spring of traction piston as load maintainer.

In the relation shown in Fig. 9 (A), a load maintainer S side vertically loads piston P, and D is side-prominent to one for axle.In this relation, if the loading force that overcomes load maintainer S to opposite side push shaft D, then piston P opens import I and exports being communicated with of O.On the other hand, if the loading force of yielding to load maintainer S to a layback axle D, then piston P closes import I and outlet being communicated with of O.

In addition, in the relation shown in Fig. 9 (B), load maintainer S loads piston P along a side, and axle D is outstanding to opposite side.In this relation, if the loading force that overcomes load maintainer S to opposite side pulling shaft D, then piston P opens import I and exports being communicated with of O.On the other hand, if the loading force of yielding to load maintainer S to a thruster axle D, then piston P closes import I and outlet being communicated with of O.

And then in the relation shown in Fig. 9 (C), load maintainer S loads piston P along opposite side, and D is side-prominent to one for axle.In this relation, if the loading force that overcomes load maintainer S to a layback axle D, then piston P closes import I and exports being communicated with of O.On the other hand, if the loading force of yielding to load maintainer S to opposite side push shaft D, then piston P opens import I and outlet being communicated with of O.

In addition, in the relation shown in Fig. 9 (D), load maintainer S loads piston P along opposite side, and axle D is outstanding to opposite side.In this relation, if the loading force that overcomes load maintainer S to opposite side push shaft D, then piston P closes import I and exports being communicated with of O.On the other hand, if the loading force of yielding to load maintainer S to a layback axle D, then piston P opens import I and outlet being communicated with of O.

In the middle of these, the relation shown in Fig. 9 (A) is best.If like this, then can adopt general pushing spring as load maintainer S, can make piston P close being communicated with of import I and outlet O by this loading force that pushes spring, axle D is pushed to the cam of opposite side in order to open import I and export being communicated with of O, can adopt the loading force that overcomes load maintainer S on the other hand.Because this cam is made in order to open import I and with being communicated with of O of outlet axle D is pushed to the structure of opposite side, thus relatively simple for structure, can make the manufacturing cost cheap of switch valve.

If with the most preferred embodiment of the 1st invention, then can adopt fluid is flushing water, just outlet is connected to the just structure of tool of the Western-style flushing of no water tank that does not have to have wc flushing cistern.If like this, even then in the high level or the depth underground of building, also can by switch valve carry out effectively to the Western-style flushing of no water tank that do not have just to have wc flushing cistern just tool feedwater and stop feedwater.

{ the 2nd invention }

In addition, in above-mentioned existing just tool flushing waterworks, because employing makes the electromagnetic valve that is rich in flexual dividing plate action as valve system, dividing plate can be out of shape by the operation of electromagnetic valve, so exist following problem.

That is to say that electromagnetic valve is to produce magnetic attracting force by the excitation that causes to electromagnet energising, the movable body that permeability magnetic material makes is arranged in the magnetic attraction electromagnetic valve and make opening of valves.Therefore in this electromagnetic valve,, also exist the problem of residual bigger residual magnetic in movable body even the electromagnet demagnetization.Therefore, if,, all exist the unsettled danger of action of valve system then regardless of 1 hydraulic pressure that acts on the water inlet just implement of the measure of the residual magnetic of elimination to the influence of the electromagnetic valve of these tool flushing waterworks.

In addition, electromagnetic valve is that standard-sized sheet or full cut-off are prerequisite with its valve opening, can not remain on midway interstage to valve opening.Therefore, in this just tool flushing waterworks, for making flushing water constantly continue slightly to flow in order to prevent the freezing of flushing water in the water supply system in situations such as cold, electromagnetic valve also can't be realized this user mode.

And then electromagnetic valve is in general expensive than motor etc., causes the expensive of just tool flushing waterworks.

The 2nd invention makes in view of above-mentioned actual conditions, a kind of stabilizing that can realize the action of valve system is provided, and the freezing of flushing water can prevent cold the time, and more just tool wash waterworks as the 2nd problem to be solved.

Cam gear 190 shown in Fig. 3 and Fig. 4 is by being fixed in two

switch valve

101B, 101C, there is outstanding forward carriage 190b at two ends, with the camshaft 190a that on this carriage 190b, can rotate and keep with horizontal state, with be fixed on this camshaft 190a, the cam surface by periphery can be formed with contacted the 1st, 2 cams 191,192 of

axle

106B, 106C of each

switch valve

101B, 101C.

Change-speed gearing and motor are housed in the drive unit 194, can rotate the camshaft 190a of drive cam arrangement 190 by the control of controller.

Handle 195 is installed on the drive unit 194, manually the camshaft 190a of rotating cam device 190.

Just in the tool, flushing water supplies to waterworks 107 via water-supply source, stopcock, flexible pipe 1-103, branch unit 1-102 and conduit 1-101 in the Western-style flushing of no water tank of formation as above-mentioned.In waterworks 107, as long as the push-botton operation that the user does not carry out the flushing of bedpan 180, two

switch valve

101B, 101C just are in and close.That is to say,, then pass through the loading force of pushing helical spring 105 if illustrate with the switch valve 101 shown in Fig. 1 and Fig. 2, piston 103 side vertically, just arrow Y1 direction moves.Therefore, piston 103 is seated at the seat surface 102a of valve bonnet 102, the outer peripheral face 103f sealing water inlet 121 of piston 103, and an end face 103a of piston 103 sealing delivery port 123.Therefore, water inlet 121 was closed with being communicated with of delivery port 123, did not supply with flushing water and just had in the main body 108 in Western-style.

And, when carrying out the flushing of bedpan 180,, come the motor of driver 194, rotation drive cam shaft 190a by the signal of controller based on user's push-botton operation.Therefore, the axle 106B of the downward push switch valve of the cam surface of the 1st cam 191 101B opens switch valve 101B.That is to say, if illustrate with the switch valve 101 shown in Fig. 1 and Fig. 2, then by the 1st cam 191 the opposing party vertically, the axle of arrow Y2a direction pushing just 106.So, pushing helical spring 105 elastic shrinkage, piston 103 other direction vertically, just arrow Y2 direction moves.As shown in Figure 2, piston 103 leaves the seat surface 102a of valve bonnet 102, opens being communicated with of water inlet 121 and delivery port 123.Waterworks 107 via the edge with conduit 198 the flushing water water flowing road, edge 183 of feeding water, the internal face of flushing pelvic part 182.

The cam surface of the 1st cam 191 is the axle 106B of push switch valve 101B no longer downwards, after the closing of switch valve 101B and above-mentioned switch valve 101 similarly closed, the axle 106C of the downward push switch valve of the cam surface of the 2nd cam 192 101C, same with above-mentioned switch valve 101, switch valve 101C is opened.Therefore, waterworks 107 produce siphonage forcibly via spraying with conduit 197 the flushing water injection nozzle 187 that feeds water in water turn of bilge 185.

Then, the cam surface of the 2nd cam 192 is the axle 106C of push switch valve 101C no longer downwards, after the closing of switch valve 101C and above-mentioned switch valve 101 closed equally, the cam surface of the 1st cam 191 is the axle 106B of downward push switch valve 101B once more, same with above-mentioned switch valve 101, switch valve 101B is opened.Therefore, waterworks 107 are fed to water flowing road, edge 183 to flushing water via the edge with conduit 198, make pelvic part 182 water shutoffs.

So, in two switch valve 101B, the 101C of embodiment, can regulate the aperture that is communicated with of water inlet and delivery port by the peripheral operation of axle 106B, 106C.Below, if illustrate, then because of carry out the switch that be communicated with of water inlet 121 by piston 103, so piston 103 is under pressure along opposite side from the flushing waters in the delivery port 123 with delivery port 123 with the switch valve 101 shown in Fig. 1 and Fig. 2.At this moment, there is not flexual piston 103 can not be out of shape along opening direction because of this pressure to opposite side.But, the space of the slip usefulness of piston 103 is set, because of making piston 103 axial slidings, this pressure to opposite side hindered.This point is in switch valve 101, because the opposite side at piston 103 forms pressure payment chamber 104, the side and this pressure payment chamber 104 that are communicated with piston 103 by a plurality of through hole 104a, move to pressure payment chamber 104 from delivery port 123 via through hole 104a so be present in the flushing water of a side of piston 103, realize the balance of pressure of flushing water of a side of the pressure of the flushing water in the pressure payment chamber 104 and piston 103, eliminate or reduce both pressure reduction.Guarantee the axial sliding of piston 103 with this.Therefore, in this switch valve 101, action response is stable, and when being used to not have the Western-style flushing of water tank and just having, the validity at aspects such as detergencies can improve.

In addition, in the switch valve 101 of embodiment,, each through hole 104a is set so can connect vertically simply because on piston 103, form through hole 104a.And, because on piston 103, connect vertically through hole 104a is set, so the flushing water that moves in through hole 104a is not subjected to resistance when piston 103 slides, the sliding of piston 103 improves.

And then, in the switch valve 101 of embodiment, because the water inlet 121 of valve bonnet 102 is opened on the side face of piston 103, the delivery port 123 of valve bonnet 102 is opened on the end face of an axial side of piston 103, so piston 103 can not be subjected to from the pressure of the flushing water in the water inlet 121 along opposite side, even because of switch valve 101 employed environment etc. make the hypertonia of the flushing water in the water inlet 121 or low excessively, the sliding of piston 103 does not change yet thereupon.

In addition, because as external manipulation mechanism, adopt and be fixed in piston 103 and outstanding from valve bonnet 102, overcome the axle 106 that pushing helical spring 105 slides piston 103 vertically, so there is no need the electromagnetic valve that adopts existing switch valve such, can make cheap for manufacturing costization of switch valve 101.Particularly, the Western-style flushing of no water tank shown in just in the tool, in an embodiment because use pair of

switches valve

101B, 101C, so an effect is very big.In addition, can use the 1st, 2 cams 191,192 that are fixed in a camshaft 190a to come these switch valves of

switch

101B, 101C, this effect is bigger.

And then, in the switch valve 101 of embodiment, because pushing helical spring 105 loads piston 103 side vertically, axle 106 is side-prominent along one, so adopt less expensive pushing helical spring 105, the loading force by this pushing helical spring 105 can make piston 103 close being communicated with of water inlet 121 and delivery port 123.On the other hand, for open being communicated with of water inlet 121 and delivery port 123, can adopt overcome pushing helical spring 105 loading force the cams 170 of axle 106 along opposite side pushing usefulness.Because this cam 170 make for open water inlet 121 with being communicated with of delivery port 123 structure along opposite side pushing axle 106, so relatively simple for structure, can make cheap for manufacturing costization of switch valve 101.

In addition, in the switch valve 101 of embodiment, because can open-closing velocity by at random setting with the action of the piston 103 of axle 106 via cam 170, even so flow through with the flushing water of big flow, also can prevent scram, therefore can prevent the generation of water hammer, suppress noise etc.

And then, in the switch valve 101 of embodiment, even open fully because small-sized piston 103 also can be when flushing water low pressure moves by it, so be not easy to produce the pressure loss, nor must maximize, given play to the just good installation of tool of the picture Western-style flushing of no water tank.

Just in the tool, flushing water is via water-supply source, stopcock, flexible pipe 221, branch unit 202 and supply to waterworks 203 for water conduit 223 in the Western-style flushing of no water tank that constitutes as mentioned above.In waterworks 203, the flushing of carrying out Western-style bedpan 211 of just having a main body 201 is not as long as the user has action button, and two

switch valve

204J, 204R just close.That is to say that if illustrate with Figure 14 and Figure 15, then piston 246 is by a loading force side vertically of pushing helical spring 252, just arrow Y1 direction moves.Therefore, as shown in figure 14, piston 246 is seated at the seat surface 241x of valve bonnet 241, the outer peripheral face sealing water inlet 242 of piston 246, and an end face 246a of piston 246 sealing delivery port 243.Therefore, being communicated with between water inlet 242 and the delivery port 243 is closed, and flushing water is not just had a main body 201 and supplied with to Western-style.

And, when carrying out the flushing of bedpan 201,, coming the motor 271 of driver 207 by the signal of controller based on user's push-botton operation, axis of rotation 283 is driven in rotation.Therefore, the cam surface of the 1st cam 285 pushes the axle 247 of edge with switch valve 204R downwards, and the edge is opened with switch valve 204R.If illustrate with Figure 14 and Figure 15, then push helical spring 252 elastic shrinkage, piston 246 other direction vertically, just arrow Y2 direction moves.As shown in figure 15, piston 246 leaves the seat surface 241x of valve bonnet 241, opens being communicated with between water inlet 242 and the delivery port 243.Therefore, waterworks 203 via the edge with conduit 219 the flushing water water flowing road, edge 212 of feeding water, the internal face of flushing pelvic part 210.

Along with the driving of cam gear 208, the cam surface of the 1st cam 285 pushes the axle 247 of edge with switch valve 204R no longer downwards, and the edge is closed with switch valve 204R.Then, the cam surface of the 2nd cam 286 pushes the axle 247 that sprays with switch valve 204J downwards, sprays to be opened with switch valve 204J.Therefore, waterworks 203 produce siphonage forcibly via spraying with conduit 218 the flushing water injection nozzle 215 that feeds water in water turn of bilge 214.

Then, along with the driving of cam gear 208, the cam surface of the 2nd cam 286 pushes the axle 247 that sprays with switch valve 204J no longer downwards, sprays and closes with switch valve 204J.Then, the cam surface of the 1st cam 285 pushes the axle 247 of edge with switch valve 204R once more downwards, and the edge is opened once more with switch valve 204R.Therefore, waterworks 203 via the edge with conduit 219 the flushing water water flowing road, edge 212 of feeding water, make pelvic part 210 water shutoffs.

Illustrate with Figure 14 and Figure 15 below, because carry out being communicated with of switch water inlet 242 and delivery port 243, so piston 246 is subjected to the pressure from the opposite side of the flushing water in the delivery port 243 by piston 246.At this moment, there is not flexual piston 246 can not produce distortion to opposite side because of this pressure to opposite side.But, be provided with the space of the slip usefulness of piston 246, because of making piston 246 axial slidings, this pressure to opposite side hindered.This point is in

switch valve

204J, 204R, because the opposite side at piston 246 forms pressure payment chamber 250, the side and this pressure payment chamber 250 that are communicated with piston 246 by a plurality of through holes 251, move to pressure payment chamber 250 from delivery port 243 via through hole 251 so be present in the flushing water of a side of piston 246, realize the balance of pressure of flushing water of a side of the pressure of the flushing water in the pressure payment chamber 250 and piston 246, eliminate or reduce both pressure reduction.Therefore guarantee the axial sliding of piston 246.

Shown in Figure 59 (A), the cam 524 of water flowing road, edge 2 usefulness forms with respect to axis of rotation 523 and is the outstanding to both direction of symmetry.In contrast, shown in Figure 59 (B), the cam 525 of spray-hole 5 usefulness forms outstanding to a direction with respect to axis of rotation 523.In addition, cam 525 projected directions of the cam 524 of edge water flowing road 2 usefulness and spray-hole 5 usefulness are located on the axis of rotation 523 with staggering 90 degree mutually.

If make cam 524,525 with axis of rotation 523 rotation by the motor shown in Figure 58 520, then valve shaft 517,518 bears box 526,527 with cam and moves vertically, makes switch valve 515,516 switching manipulations.Said motor 520 usefulness can be controlled to the anglec of rotation angle of regulation, for example gear motor, stepper motor etc.In addition, have the control device C of the action usefulness of rotary encoder E that the rotation amount that monitors axis of rotation 523 uses or control motor 520 in position.And, on rotary encoder E, be formed with window portion f, can the Visual Confirmation anglec of rotation turned position of cam 524,525 just.

Switch shown in Figure 58 along with the revolution switch valve 515 of cam 524, the flushing water of being supplied with to water flowing road, edge 2 from water service pipe 512 is shown in Figure 59 (A), flow in the switch valve 515 by inflow entrance 513, the water service pipe Q of branch to water flowing road, edge 2 supplies with via vacuum circuit breaker 519.On the other hand, switch shown in Figure 58 along with the revolution switch valve 516 of cam 525, the flushing water of being supplied with to spray-hole 5 flows into the opposing party's switch valve 516 from inflow entrance 514 shown in Figure 59 (B), the water service pipe R of branch to spray-hole 5 usefulness supplies with via vacuum circuit breaker 519.

The manual-operating mechanism that the switch of manual operation switch valve 515,516 is used is shown in Figure 58, gear 550 is connected with axis of rotation 541 on being arranged on handle 540, this gear 550 meshes than different gear 551 with gear, is connected with the output gear 522b of clutch 522.Clutch 522 is taken as one-way clutch, can freely makes the rotary manipulation of axis of rotation 523 for motor 520 by manual-operating mechanism with this.Thereby manual operation does not act on load on the motors 520 such as gear motor.

Flow the action of switching device shifter 510 below with Figure 59～62 open fires.In addition, in any one drawing, the switch valve 515 of water flowing road, edge 2 usefulness of the sectional view of the II-II line of figure (A) expression Figure 58, the switch valve 516 that spray-hole 5 water flowings of the sectional view of the I-I line of figure (B) expression Figure 58 are used.Figure 59 represents A-stage switch valve 515, the 516 non-water flowing state of all closing just.In the figure, the valve body V in the switch valve 515,516 loads to the direction of taking one's seat by spring S, closes closed channel.

If indicate just tool flushing under above-mentioned state, then the control device C shown in Figure 58 drives motor 520, makes cam 524,525 turn over 90 degree counterclockwise from the state of Figure 59, becomes the state of Figure 60.So shown in Figure 60 (A), only the cam of edge water flowing road 2 one sides bears the rotation of box 526 by cam 524 and moves to the right-hand of drawing, via valve shaft 517 valve body V is disseated.With this, flushing water flows into switch valve 515 from a water service pipe 512 by inflow entrance 513, supplies with to water flowing road, edge 2 via vacuum circuit breaker 519, and flushing water is emitted the flushing of carrying out initial bedpan 4 to bedpan 4 as a result.

The flushing of bedpan 4 is set for by the predefined time (for example 7 seconds) and is undertaken.That is to say that if begin to have passed through certain hour from the flushing of bedpan 4, then the control device C shown in Figure 58 makes motor 520 startings, make cam 524,525 further turn over 90 degree counterclockwise, become the state of Figure 61 from the state of Figure 60.Shown in Figure 61 (B), because the cam of cam 525 pushing spray-holes 5 one sides bears box 527 and makes it to move right, so by valve shaft 518 valve body V is disseated, switch valve 516 can water flowing.As a result, flushing water supplies to spray-hole 5, and beginning is to the ejection of discharge pipe 3.Simultaneously, shown in Figure 61 (A), bear box 526 because the jut of cam 524 stops to push the cam of water flowing road, edge 2 one sides, so the valve body V of switch valve 515 is loaded by spring S and takes one's seat, the feedwater to water flowing road, edge 2 stops.

To the supply of the flushing water of spray-hole 5 only need keep producing forcibly the needed time of siphonage (for example about 7 seconds) just passable.Thereby, if passed through certain hour to the feedwater of spray-hole 5, the motor 520 shown in Figure 58 is driven make cam 524,525 turn over 90 degree from beginning, become the state of Figure 62.At this moment, shown in Figure 62 (B), the valve body V of switch valve 516 takes one's seat and stops to the feedwater of spray-hole 5, and shown in Figure 62 (A), the valve body V of switch valve 515 disseats and supplies with flushing waters from water flowing road 2, edge to bedpan 4.So, after having discharged flushing water by the generation of siphonage, by from water flowing road 2, edge to bedpan 4 supply flushing waters, can in bedpan 4, form water seal.Also is to keep certain hour (for example 7 seconds) just passable by water flowing road 2, edge to the process of bedpan 4 supply flushing waters.Begin from water flowing road 2, edge after the flushing water supply of bedpan 4,, then make cam 524,525 rotations, turn back to the A-stage of Figure 59 by the motor shown in Figure 58 520 if passed through certain hour.

Shown in Figure 87, drive unit 809 makes the 1st, 2 switch valves 851,852 switches, by the cam gear 890 that is configured in the 1st, 2 switch valves 851,852 tops with the motor apparatus 895 of cam gear 890 action is formed.Cam gear 890 comprises with level and can remain on the axis of rotation 892 on the not shown carriage that is fixed in the 1st, 2 switch valves 851,852 rotatably and be fixed in the 1st, the 2nd cam 893,894 of axis of rotation 892.Motor and the change-speed gearing that the rotary speed that makes motor reduces are installed in the motor apparatus 895, can rotate driving axis of rotation 892 by the control of controller.The handle 896 that manual operation is used is installed, the manual axis of rotation 892 of rotating cam device 890 of situation such as when having a power failure on drive unit 809.

Shown in Figure 83, in the washroom, water service pipe 832 is installed on the wall 834, at the front end of water service pipe 832 stopcock 831 is installed.Water service pipe 832 is connected to the water portion 818 that is subjected to via the flexible pipe 830 as tube connector.Under this state, shown in Figure 87, the flushing water of water service pipe 832 is via stopcock 831, flexible pipe 830 and be subjected to water portion 818 to supply to the 1st port 862 of switch valve 805.Thereby the water inlet that 862 conducts of the 1st port are connected with water service pipe 832 plays a role.

Be located at Western-style when just having on the main body 801 as attached apparatus at the local douche device 8100 of function of part with flushing human body, local douche device 8100 comprises the water-supply valve 8102 that is connected to the 2nd port 872 of switch valve 805 via path 8102c, be connected to water-supply valve 8102 and in establish the reservoir 8104 of electric heater of heating flushing water, and to the jet blower that can stretch 8106 of the flushing water of the part of the human body that is seated at toilet seat ejection reservoir 8104.The 2nd port 872 of switch valve 805 is connected with the water-supply valve 8102 of local douche device 8,100 one sides, has the function as the admission port of local douche device 8100 usefulness that feed water.

In the Western-style flushing of no water tank that constitutes as mentioned above just in the tool, as long as the user does not carry out the switching manipulation of the flushing of pelvic part 810, just two switch valves 851,852 of flusher 804 of having just cut out, and the flushing water of water service pipe 832 does not supply to water flowing road 812, edge and injection nozzle 815.That is to say that in Figure 87, the piston 864 of the 1st, 2 switch valves 851,852 is seated at the seat surface 861c of valve bonnet 861 and closes, the 1st port 862 was blocked with being communicated with of delivery port 863, and the 1st port 862 was blocked with being communicated with also of delivery port 873.

In addition, at this in the Western-style flushing tool of no water tank, as previously mentioned, the 1st port 862 of switch valve 805 and the 2nd port 872, with irrelevant to the supply of the flushing water on water flowing road, edge 812-stop to supply with, that is to say has nothing to do with the switch motion of switch valve 852 with the edge is being interconnected all the time.Equally, the 1st port 862 of switch valve 805 and the 2nd port 872 with irrelevant to the supply of the flushing water of injection nozzle 815-stop to supply with, that is to say with the on-off action of spraying with switch valve 851 irrespectively be interconnected all the time.Therefore, the 1st port 862 of the switch valve 805 if flushing water of water service pipe 832 feeds water then not only automatically feeds water to respectively to spray with switch valve 851 and edge and uses switch valve 852 both sides, but also the 2nd port 872 of the switch valve 805 that automatically feeds water.Therefore, the reservoir 8104 that can automatically automatically also feed water and be communicated with the local douche device 8100 of the 2nd port 872 via water-supply valve 8102.

When using local douche device 8100, by signal based on the controller of user's switching manipulation, the spray nozzle part of the front end of jet blower 8106 is ejected into the warm water of reservoir 8104 part of human body and washes the part near the part that is seated at the user of toilet seat.Local flushing one finishes, and the nozzle of the front end of jet blower 8106 is just return.

When reducing along with the flushing water of the use reservoir 8104 of local douche device 8100, the controller that detects this situation by level sensor is opened water-supply valve 8102.Therefore, flushing water from water service pipe 832, use the switch of switch valve 851 irrelevant with the edge with switch valve 852 and injection, supply to the reservoir 8104 of local douche device 8100 via the 1st port 862 that is subjected to water portion 818, switch valve 805, access 876, intermediate connection road the 875, the 2nd port 872 and water-supply valve 8102.

And, after having washed the part, carry out the flushing of pelvic part 810.In the case, come CD-ROM drive motor device 809 based on user's switching manipulation according to the signal of controller, the axis of rotation 892 of cam gear 890 is driven in rotation.Therefore, the cam surface of cam 894 is along the axle 868 of other direction arrow Y2 direction pushing just edge with switch valve 852, and pushing helical spring 867 is with regard to elastic shrinkage, and piston 864 moves along arrow Y2 direction.Thus, the edge leaves the seat surface 861c of valve bonnet 861 with the piston 864 of switch valve 852, opens being communicated with of the 1st port 862 and delivery port 863.Thus, the edge with switch valve 852 flushing water via the edge with the conduit 816 water flowing road, edge 812 of feeding water, the internal face of flushing pelvic part 810.

Then, cam 894 pushes the axle 868 of edge with switch valve 852 no longer downwards, after the edge was closed with switch valve 852, the cam surface of cam 893 sprayed the axle 868 of using switch valve 851 along other direction arrow Y2 direction pushing just, made to spray and opened with switch valve 851.Therefore, spray the seat surface 861c that leaves valve bonnet 861 with the piston 864 of switch valve 851, spray and open with switch valve 851, the 1st port 862 is communicated with via intermediate connection road 875 with delivery port 873.Therefore, spray with switch valve 851 flushing water via injection, produce siphonage forcibly with conduit 817 injection nozzle 815 that feeds water.

Then, the cam surface of cam 893 no longer pushes the axle 868 that sprays with switch valve 851, and after injection was closed with switch valve 851, cam 894 pushed the axle 868 of edge with switch valve 852 once more, and the edge is opened with switch valve 852.Thus, flushing water with the conduit 816 water flowing road, edge 812 of feeding water, makes pelvic part 810 water shutoffs via the edge.So the flushing of pelvic part 810 finishes.

As mentioned above, the 2nd port 872 of switch valve 805 with irrelevant to the supply of the flushing water on water flowing road, edge 812-stop to supply with, with irrelevant to the supply of the flushing water of injection nozzle 815-stop to supply with, is being communicated with the 1st port 862 in addition all the time.Thereby, shown in Figure 87, if the 1st port 862 of switch valve 805 is coupled together with water service pipe 832 via stopcock 831 and flexible pipe 830, then flushing water with supply with to the supply of the flushing water on water flowing road, edge 812-stop and irrespectively supplying to the 2nd port 872 to the supply of the flushing water of injection nozzle 815-stop to supply with.Therefore, can supply with flushing water to the reservoir 8104 of local douche device 8100 via switch valve 805.

As a result, because do not need tube connector that local douche device 8100 and water service pipe 832 are directly coupled together, so unlike the prior art, can prevent to be provided with side by side many tube connectors.Therefore, not only the required pipe arrangement space of tube connector can reduce, and can prevent that outward appearance is affected.

It is prerequisite that above-mentioned explanation is located under the Western-style situation of just having on the main body 801 with local douche device 8100.But, be not located under the Western-style situation of just having on the main body 801 at local douche device 8100, can be installed in the lid member 857 shown in Figure 87 that to block the 2nd port 872 on the 2nd port 872 of switch valve 805 just passable with dismantling.

Then, the axle 921 that sprays with switch valve 906 makes piston 913 declines, opens being communicated with of main access 911b and secondary access 911c.Thus, the flushing water of big flow flows to Western-style injection nozzle of just having a main body 901, produces siphon effect forcibly.Then, piston 913 is yielded to the loading force of pushing spring 912 and is risen, and closes being communicated with of main access 911b and secondary access 911c.

Then, the edge makes piston 916 descend with the axle 923 of switch valve 907 once more, opens being communicated with of main access 914b and secondary access 914c.Thus, the flushing water of big flow flows to Western-style water flowing road, edge of just having a main body 901, carries out water shutoff.Then, piston 916 is yielded to the loading force of pushing spring 915 and is risen, and closes being communicated with of main access 914b and secondary access 914c.So Western-style a series of flushings of just having main body 901 finish.

Under cryogenic conditions such as cold district, continuing after closing the master valve of water pipe, to open the pipe arrangement of the not shown usefulness that discharges water under the obsolete state.Then, input by manual or switch makes cam gear 908 actions, make piston 913,916 declines by spraying with spools 921,923 of switch valve 907, open being communicated with of main access 911b, 914b and secondary access 911c, 914c with switch valve 906 and edge.Carry out in main access 911b, 914b and secondary access 911c, the 914c and the discharging water of the flushing water in their downstream with this.

At this moment, spray with switch valve 906 and edge switch valve 907, because the bottom surface of main access 911b, 914b forms to water inlet 911a with descending, therefore the flushing water of inside flows out to water inlet 911a, the not residual flushing water in inside.In addition, the flushing water of guiding to water inlet 911a is along flexible pipe 903 and stopcock 904 adverse currents, and is discarded to underground via the pipe arrangement of the usefulness that discharges water.Therefore, in this case, not residual flushing water in main access 911b, 914b and secondary access 911c, 914c has prevented that flushing water from freezing therein.

Close the pipe arrangement of the usefulness that discharges water, the master valve of the deferent of fetching boiling water next time when using the Western-style flushing of no water tank just to have.The flushing water that water pipe is 905 li supplies to via stopcock 904 and flexible pipe 903 just has a flusher 902, makes normal use become possibility.

Thereby, if with the injection of present embodiment with switch valve 906 and edge with switch valve 907, then because the damage of freezing to cause that does not produce flushing water after discharging water, can promptly use next time, so can not go wrong in using in that ending of next time is normal.

1004R, 1004J switch.

On manual handle 1075, be provided with the grip sensor 1077 that plays a role as testing agency.Grip sensor 1077 detects the user and contacts with manual handle 1075, makes the situation that produces micro angular displacement on the manual handle 1075, is made of the pressure sensing type touch sensor.

In being on the housing of one shown in Figure 98 and Figure 99, be provided with the just tool flushing button 1096 shown in Figure 101 with outer cover 1032.Just by the user's push that is landed on the toilet seat, CD-ROM drive motor 1071 carries out the flushing of Western-style bedpan 1011 of just having a main body 1001 as normal mode with button 1096 for tool flushing.

Controller 1009 comprises the input processing circuit 1090 of handling input signal, based on from the signal of input processing circuit 1090 and the control processing circuit 1091 of the interior dress CPU of output signal, with based on from the signal of control processing circuit 1091 and export the output processing circuit 1092 of control signal, and stored routine and memory of data 1093.Tool flushing next at one's convenience is used the flushing commencing signal S1 of button 1096 and is input to the input processing circuit 1090 of controller 1009 from the shake-up signal S2 of grip sensor 1077.If the user presses just tool flushing with button 1096, be input to controller 1009 from the tool flushing with button 1096 just then wash commencing signal S1.Based on flushing commencing signal S1, the output processing circuit 1092 of motor control signal S10 slave controller 1009 is input to motor drive circuit 1071c, and motor 1071 is controlled.

In addition, if user's finger tip contacts with manual handle 1075, then touch signal S2 and be input to controller 1009 from grip sensor 1077.Based on touching signal S2, the output processing circuit 1092 of slave controller 1009 produces motor control signal S10 and pulsed sound generation signal S20.Motor control signal S10 is input to motor drive circuit 1071c, and motor 1071 is controlled.Pulsed sound generation signal S20 is input to the electronics sound and produces

circuit

1072c, and 1072 actions of electronics sound generation device produce interrupted electronics sound.

The Western-style flushing of no water tank that constitutes as mentioned above just tool Western-style just have in the main body 1001, flushing water is via water service pipe 10100, stopcock 10102, flexible pipe 1021, branch unit 1002 and supply to for water conduit 1023 just to have flusher 1003.Just having in the flusher 1003, as long as the user carries out the just tool flushing of flushing of bedpan 1011 with the operation of button 1096, two

switch valve

1004J, 1004R just close.That is to say, if illustrate with Figure 100, then loading force vertically the side of piston 1046 by spring 1052 just arrow Y1 direction move, piston 1046 is seated at the seat surface 1041x of valve bonnet 1041, the outer peripheral face sealing water inlet 1042 of piston 1046.Therefore, water inlet 1042 was closed with being communicated with of delivery port 1043, and flushing water does not supply to Western-style bedpan 1011 of just having a main body 1001.

Just the situation of washing bedpan 1011 with normal mode describes.In the case, based on the operation that user's just tool washes usefulness button 1096, controller 1009 outputs to motor drive circuit 1071c to motor control signal S10, and the motor 1071 of driver 1007 rotates axis of rotation 1083.The cam surface of the 1st cam 1085 pushes the axle 1047 of edge with switch valve 1004R downwards thus, and the edge is opened with switch valve 1004R, carries out " edge feedwater ".If illustrate with Figure 100, spring 1052 elastic shrinkage then, piston 1046 other direction vertically just arrow Y2 direction moves.Piston 1046 leaves the seat surface 1041x of valve bonnet 1041 thus, and water inlet 1042 is communicated with delivery port 1043.If the edge is opened with switch valve 1004R like this, then flushing water supplies to water flowing road, edge 1012 via the edge with conduit 1019, the internal face of the pelvic part 1010 of flushing bedpan 1011.

Along with the driving of cam gear 1008, the cam surface of the 1st cam 1085 pushes the axle 1047 of edge with switch valve 1004R no longer downwards, and the edge is closed with switch valve 1004R.Then, the cam surface of the 2nd cam 1086 pushes the axle 1047 that sprays with switch valve 1004J downwards, makes to spray with switch valve 1004J to open and carry out " spray and feed water ".Open with switch valve 1004J if spray like this, then flushing water supplies to injection nozzle 1015 via spraying with conduit 1018, produces siphonage forcibly at water turn of bilge 1014.

Then, along with the driving of cam gear 1008, the cam surface of the 2nd cam 1086 pushes the axle 1047 that sprays with switch valve 1004J no longer downwards, sprays and closes with switch valve 1004J.Then, the cam surface of the 1st cam 1085 pushes the axle 1047 of edge with switch valve 1004R once more downwards, and the edge is opened once more with switch valve 1004R and carried out " edge feedwater ".Flushing water supplies to water flowing road, edge 1012 via the edge with conduit 1019 thus, and the pelvic part 1010 of bedpan 1011 is by water shutoff.

, shown in Figure 99, because the fault of motor 1071 or power failure etc. when the motor 1071 of drive unit 1007 can't be moved, the manual handle 1075 that user's operation is exposed from outer cover 1032.That is to say that if the user shakes by manually making manual handle 1075, then the axis of rotation 1083 of cam gear 8 is because of manually rotating, the 1st cam the 1085, the 2nd cam 1086 rotates.Situation with motor 1071 drivings is the same thus, the edge is opened with switch valve 1004R carried out " edge feedwater ", and flushing water is supplied to water flowing road, edge 1012 via the edge with conduit 1019, the internal face of the pelvic part 1010 of flushing bedpan 1011.And then, along with manual operation, the cam surface of the 2nd cam 1086 pushes the axle 1047 that sprays with switch valve 1004J downwards, make to spray and open and carry out " spray and feed water " with switch valve 1004J, flushing water is supplied to injection nozzle 1015 via spraying with conduit 1018, can produce siphonage forcibly at water turn of bilge 1014.Then, the edge is opened once more with switch valve 1004R carried out " edge feedwater ", can make pelvic part 1010 water shutoffs of bedpan 1011.

Because manual handle 1075 is arranged to expose from outer cover 1032 like this, thus not only when unusual, and since unused user with also wrong operation exception after an action of the bowels with the possibility of manual handle 1075.This point at this in the Western-style flushing tool of no water tank, even it is uncomfortable for example user, and hypothesis is not when noticing the just tool flushing that is positioned at other places with the existing of button 1096, the user only need operate manual handle 1075 lightly, and then grip sensor 1077 detects the user and contacts manual handle 1075.Therefore, controller 1009 drives motor 1071 via motor drive circuit 1071c and manual handle 1075 is shaken, and carries out the flushing of Western-style bedpan 1011 of just having a main body 1001.In addition, controller 1009 produces circuit 1072c via the electronics sound and makes the action of electronics sound generation device, produces interrupted electronics sound.

That is to say that shown in Figure 101, controller 1009 is input to motor drive circuit 1071c to motor control signal S10, CD-ROM drive motor 1071 and axis of rotation 1083 rotation is driven.In addition, controller 1009 outputs to the electronics sound to pulsed sound generation signal S20 and produces circuit 1072c, makes 1072 actions of electronics sound generation device, produces interrupted electronics sound.That is to say that if the user touches manual handle 1075 lightly with finger tip, then the action of cam gear 1008 is auxiliary by motor 1071, and produces interrupted electronics sound.

As a result, with above-mentioned the same, the pushing edges are with the axle 1047 of switch valve 1004R downwards for the 1st cam 1085, and the edge is opened with switch valve 1004R and carried out " edge feedwater ".Then, the cam surface of the 1st cam 1085 pushes the axle 1047 of edge with switch valve 1004R no longer downwards, and the edge is closed with switch valve 1004R.Then, the cam surface of the 2nd cam 1086 pushes the axle 1047 that sprays with switch valve 1004J downwards, sprays and opens with switch valve 1004J, carries out above-mentioned " spraying feedwater ".Then, the cam surface of the 2nd cam 1086 pushes the axle 1047 that sprays with switch valve 1004J no longer downwards, sprays and closes with switch valve 1004J.Then, the cam surface of the 1st cam 1085 pushes the axle 1047 of edge with switch valve 1004R once more downwards, and the edge is opened once more with switch valve 1004R, carries out " edge feedwater ".

At this moment, the CPU that is installed in the controller 1009 carries out according to the control program block diagram shown in Figure 102.That is to say, in step S102, carry out initial setting.Judge in step S104 just whether the tool flushing is switched on operation with button 1096.If the user operates just the tool flushing and makes it to connect with button 1096, just then the user has a mind to wash Western-style bedpan 1011 of having a main body 1001 with normal rinse mode.Then, whether whether the axis of rotation 1083 of judging cam gear 1008 in step S106 be water discharge mode just at origin position.If not water discharge mode, then enter step S108, make motor 1071 drive and make axis of rotation the 1083, the

1st cam

1085 and 1086 rotations of the 2nd cam of cam gear 1008.Feed water by the order execution of " edge feedwater " → " spray feedwater " → " edge feedwater " as previously mentioned thus, wash the pelvic part 1010 of Western-style bedpan 1011 of just having a main body 1001.Turn back to step S104 then.

Water discharge mode is when preventing the freezing of flushing water when cold and adopted pattern.Therefore, under water discharge mode, be that condition is opened

switch valve

1004R, 1004J by trace to close stopcock 10102, discharge may remain in the flushing water in switch valve 1004R, the 1004J etc.In addition, as water discharge mode, can adopt all the time trace to open

switch valve

1004R, 1004J, time per unit makes a spot of flushing water continuous stream cross Western-style flow pattern of just having a main body 1001.

If the result of determination in step S106 is set water discharge mode for, then carry out step S106 to the operation of step S120, motor 1071 is driven a little and make axis of rotation 1083 return to origin position.At this moment, the amount of returning is stored in the memory 1093.Then, in step S122, make motor 1071 further drive and make axis of rotation the 1083, the

1st cam

1085 and 1086 rotations of the 2nd cam.Thus with above-mentioned the same, feed water by the order execution of " edge feedwater " → " spraying feedwater " → " edge feedwater ", wash Western-style bedpan 1011 of just having a main body 1001.Then, enter step S124, make the motor stored amount of returning of 1071 reverse rotations and return water discharge mode, trace is opened

switch valve

1004R, 1004J, turns back to step S104.

If being just tool flushing, the result of determination in step S104 cuts off, just then do not require to wash Western-style bedpan 1011 of having a main body 1001 with normal rinse mode with button 1096.Therefore, then carry out the operation of step S104, judge that whether manual handle 1075 is by user's operating of contacts to step S130.This judges based on the shake-up signal from the grip sensor 1077 of manual handle 1075 and carries out.If manual handle 1075 then turns back to step S104 from step S130 not by user's operating of contacts.

If manual handle 1075 by user's operating of contacts, then enters step S132, whether judgement continues stipulated time Δ T1 (for example 0.02～1 second scope) from the operating of contacts of the moment manual handle 1075 of step S130.If the operating of contacts of manual handle 1075 continues, then the intention with user's actual contact operation manual handle 1075 improves the judgement precision.Therefore, whether step S132 has the affirmation mechanism of the operating of contacts of manual handle 1075 to play a role as affirmation.So,, then enter step S134, produce the electronics sound and wait for stipulated time Δ T2 if the user continues to carry out the operating of contacts of manual handle 1075.Then, enter step S136, make motor 1071 drive and make the 1st cam 1085 and the 2nd cam 1086 to rotate.Therefore same as described above, feed water by the order execution of " edge feedwater " → " spraying feedwater " → " edge feedwater ", wash the pelvic part 1010 of Western-style bedpan 1011 of just having a main body 1001.

So in the Western-style flushing of this no water tank just in the tool, the shaking of auxiliary manual handle 1075 carried out Western-style flushing of just having a main body 1001.Therefore, in the Western-style flushing of this no water tank just in the tool, even unused user also can just be had a main body 1001 so that good operability flushing is Western-style.In addition, because can know operation, so undue rotation manual handle 1075 not can prevent misoperation or fault with auxiliary manual handle 1075 by producing the electronics sound.

(the 2nd embodiment)

Figure 103 illustrates the 2nd embodiment.The 2nd embodiment has just to have a water tank type of wc flushing cistern and wash just tool.For realizing and the position of the 1st embodiment identical functions, give identical assembly numbering.

In the Western-style flushing of no water tank that constitutes as mentioned above just in the tool, when being provided with, shown in Figure 106 and Figure 107, the person of setting is switched change-over switch 1107a according to the pipeline pressure of water pipe 1103, selects the edge with switch valve 1106a with spray opening the time with switch valve 1106b with this.

That is to say, if the pipeline pressure height of water pipe 1103 then is not provided with the person change-over switch 1107a is switched to high pressure usefulness.Therefore, the user stool with and urine with in when operating flush switch by remote controller 1108, the edge with switch valve 1106a and injection with time of opening of switch valve 1106b shown in Figure 108 (A).

Under this state, with switch valve 1106a flushing water a is discharged by opening the edge from Western-style water flowing road, edge of just having a main body 1101 at the beginning, flush away is attached to the dirt of Western-style pelvic part of just having a main body 1101.Then, make flushing water b be discharged to Western-style trap of just having a main body 1101, produce siphon effect forcibly, the discharge dirt by opening to spray with switch valve 1106b.Then, make flushing water a be discharged to Western-style water flowing road, edge of just having a main body 1101 with switch valve 1106a, form water shutoff at Western-style trap of just having main body 1101 by opening the edge once more.

At this moment, edge initial when the push button of stool usefulness is pressed is long with the time of opening of switch valve 1106a, and edge initial when the push button of urine usefulness is pressed is short with the time of opening of switch valve 1106a.On this point, stool with and urine with in, initial edge is with the asynchronism(-nization) of opening of switch valve 1106a, later injection does not have different with switch valve 1106b and edge with time of opening once more of switch valve 1106a.Particularly, no matter defecate and use and urine usefulness, the time of opening of spraying with switch valve 1106a equates.

In addition, if water pipe is a low pressure, the person then is not set change-over switch 1107a is switched to low pressure usefulness.The user stool with and urine with in when operating flush switch by remote controller 1108, the edge with switch valve 1106a and injection with time of opening of switch valve 1106b shown in Figure 108 (B).

At this moment, initial edge switch valve 1106a, the injection of following use switch valve 1106b and last edge with switch valve 1106a open the time ratio high pressure time extend.And, stool with and urine with in, same, initial edge is with the asynchronism(-nization) of opening of switch valve 1106a, later injection does not have different with switch valve 1106b and edge with time of opening once more of switch valve 1106a.Particularly, no matter defecate and use and urine usefulness, the time of opening of spraying with switch valve 1106a equates.

Therefore, in the Western-style flushing tool of no water tank, the edge is with switch valve 1106a and spray with switch valve 1106b according to opening with the corresponding time of opening suitably of the pipeline pressure of water pipe 1103 at this.That is to say, even it is low at pipeline pressure, under the weak situation of the discharge impetus of flushing water, also can by prolong the edge with switch valve 1106a and injection with the opening the time of switch valve 1106b, the dirt that accumulates in Western-style trap of just having a main body 1101 is discharged fully.Therefore, eliminate disagreeable smell, helped health.

On the other hand, at the pipeline pressure height, under the strong situation of the impetus of flushing water, by shorten the edge with switch valve 1106a with spray, be no more than with the opening the time of switch valve 1106b need the consumption flushing water.

In addition, in the Western-style flushing of this no water tank just in the tool, though stool with or urine usefulness, make the time of opening of spraying equal with switch valve 1106b.Stool might as well urinate, because guaranteed same capacity at trap with dirt, so can produce the siphon effect of degree much at one with the flushing water of same quantity delivered.Therefore, even make the time of opening of spraying equate also can discharge dirt, can avoid unhygienic effectively and consumption in vain flushing water with switch valve 1106b.In addition, make simplifying the structure of control part 1107d, and then can realize cheapization of manufacturing cost.

Thereby, in the Western-style flushing tool of no water tank, can avoid unhygienic effectively and consumption in vain flushing water at this.

{ the 12nd invention }

Below with reference to Figure 109～113 realization the 12nd inventive embodiment is described.

The Western-style flushing of no water tank of embodiment just the schematic diagram of tool shown in Figure 109.The Western-style flushing of this no water tank just tool comprises that not just not having wc flushing cistern Western-style just has a main body 1201, just has a flusher 1202, not shown heating toilet seat and not shown toilet cover.

It is Western-style that just to have a main body 1201 are ware systems.Just the flusher 1202 of having directly is connected with water pipe 1203 by flexible pipe 1205 via stopcock 1204, can wash the Western-style main body 1201 of just having by discharging flushing water a and flushing water b.

In the inside of just having flusher 1202, shown in Figure 110, have the edge with switch valve 1206a with spray and use switch valve 1206b, cam gear 1206c to be located at the edge with switch valve 1206a with spray the top of using switch valve 1206b, stepper motor 1206d is located at the side of cam gear 1206c.Cam gear 1206c drives by stepper motor 1206d, comes switching edge to use switch valve 1206b with switch valve 1206a with spraying by drive cam arrangement 1206c.

Controller 1207 is electrically connected on stepper motor 1206d, and controller 1207 can be by remote controller 1208 operations.Controller 1207 is shown in Figure 111, comprise the motor drive circuit 1207a, the position sensor 1207b that are connected with stepper motor 1206d, be connected with motor drive circuit 1207a, produce the pulse oscillation circuit 1207c of pulse signal, and be connected with position sensor 1207b, make the edge with switch valve 1206a with spray the reset reset circuit 1207d of usefulness of abnormality with switch valve 1206b.Here, position sensor 1207b detects switch valve 1206b is used at the edge with switch valve 1206a and injection on off state according to the pulse signal that is sent to stepper motor 1206d.Reset circuit 1207d be arranged on the Western-style flushing of no water tank just on the tool as informing that the warning device 1209 of mechanism is connected.

Just in the tool, controller 1207 washes processing by reset circuit 1207d and not shown storing mechanism according to the FB(flow block) shown in Figure 112 and Figure 113 in the Western-style flushing of no water tank that constitutes as mentioned above.

When the user presses the beginning push button of remote controller 1208, at first, wash processing normally according to the FB(flow block) shown in Figure 112.That is to say, in step S102, judge whether the edge all is in closed condition with switch valve 1206a and injection with switch valve 1206b.At this moment, according to the benchmark of the umber of pulse that is necessary to be sent to stepper motor 1206d, if the edge is with switch valve 1206a with spray and all be in closed condition with switch valve 1206b then be taken as " initial point ".

Here, if " initial point " then enters step S104.Stepper motor 1206d turns over certain angle and stops, and the edge is opened with switch valve 1206a.Thus, discharge flushing water within a certain period of time, dirt comes together in trap.

Then, enter step S106, judge whether the edge is in open mode with switch valve 1206a, spray whether be in closed condition with switch valve 1206b.If be here " being ", then enter step S108.Thus, stepper motor 1206d turns over certain angle and stops, and the edge is closed with switch valve 1206a, and sprays and open with switch valve 1206b.Thus, flushing water a stops, and discharges flushing water b within a certain period of time and produces siphon effect forcibly, discharges dirt.

Then, enter step S110, judge whether the edge is in closed condition with switch valve 1206a, spray whether be in open mode with switch valve 1206b.If be here " being ", then enter step S112.Thus, stepper motor 6d turns over certain angle and stops, and spray and close with switch valve 1206b, and the edge is opened with switch valve 1206a.Thus, flushing water b stops, and discharges flushing water a within a certain period of time, carries out the water shutoff of trap and handles.

Then, enter step S114, judge whether the edge is in open mode with switch valve 1206a, spray whether be in closed condition with switch valve 1206b.If be here " being ", then enter step S116.Thus, stepper motor 1206d turns over certain angle and stops, and enters step S118.Judge whether the edge all is in closed condition with switch valve 1206a and injection with switch valve 1206b.If be here " being ", then intactly become armed state, the flushing processing finishes.

On the other hand, if in step S102, step S106, step S110, step S114 and step 118 be " denying ", then is abnormality, carries out abnormality processing according to the FB(flow block) shown in Figure 113.

That is to say at first in step S202, produce to inform it is the electronics sound of abnormality by warning device 1209, and carry out reset processing to " initial point ".Enter step S204 then, judge whether normally to reset to " initial point ".Here, if be " being " then enter step S206, judge and repeated retry several times.If not enough n time of retry number then becomes " denying ", in step S208, carrying out retry by warning device 1209 demonstrations.Then, turn back to the step S102 shown in Figure 112, wash processing normally.Step S202, step S204, step S206 and step S208 in reset circuit 1207d and the storage device are resetting-mechanisms.

On the other hand, in step S206, when being judged as the retry number, become " being ", enter step S210 above n time.Therefore, can prevent from ceaselessly to repeat retry, consumed energy in vain.

And, judge that in step S210 the number of times of retry number above n time is for several times.If this number of times less than i, then is " being ", then intact armed state.In addition, surpassing n time number of times above i time if judge the retry number, then is " denying ", enters step S212, and having been undertaken by warning device 1209 becomes armed state after the demonstration of " forbidding flushing ".Therefore, can convey to the user to the situation in fault just.

In addition, in step S204, be not judged as when normally resetting to " initial point ",, enter step S214 for " denying ".Here, more normally do not reset to the number of times of " initial point ".When not enough m time of this number of times,, turn back to step S202 for " denying ".On the other hand, when this number of times surpasses m time, be " being ", enter step S216, carry out the demonstration of " forbidding flushing " by warning device 1209.Then, enter step S218, undertaken by warning device 1209 becoming armed state after the demonstration of " forcing to cut off the water ".Therefore, can prevent from ceaselessly to repeat reset processing, in vain consumed energy to " initial point ".

As mentioned above, even the Western-style flushing of no water tank at present embodiment just becomes under the situation of abnormality with switch valve 1206b with switch valve 1206a or injection at for example edge in the tool, also can detect this situation, make the edge automatically reset to closed condition with switch valve 1206b with switch valve 1206a and injection by reset circuit 1207d by position sensor 1207b.

Thereby, in the Western-style flushing tool of no water tank, can automatically stop feedwater at this, can not consume flushing water in vain.

In addition, in reset circuit 1207d etc. because Western-stylely just have a main body 1201 and carry out water shutoff and handle, so even at edge for example with switch valve 1206a or spray under the situation with switch valve 1206b generation abnormality, also can prevent via the gutter peculiar smell of emerging.

And then, in reset circuit 1207d etc., because carrying out after Western-style normal flushing of just having main body 1201 handles, make the edge become closed condition with switch valve 1206b with switch valve 1206a or injection, even, also can carry out once Western-style normal flushing of just having main body 1201 at least and handle so take place with switch valve 1206b under the situation of abnormality with switch valve 1206a or injection at the edge.Therefore, dirt can be not residual, can prevent to produce disagreeable smell, and help health.

In addition, if owing to surpass certain number of times retry then reset circuit 1207d etc. can make the edge stop down in off position with switch valve 1206b with switch valve 1206a or injection, so neither can ceaselessly repeat retry, can finally not become flushing water again and not arrhea moving state.Therefore, energy can be prevented to waste in vain, waste flushing water in vain can also be prevented.

Controller 1307 is electrically connected on stepper motor 1306d, and controller 1307 can be operated by remote controller 1308.Controller 1307 is shown in Figure 116, comprise the motor drive circuit 1307a that is connected with stepper motor 1306d, light detects the anglec of rotation of stepper motor 1306d, the pulse counting equipment 1307c of the counting mechanism of the umber of pulse of the position sensor 1307b of generation L signal and H signal, conduct counting stepper motor 1306d, and be connected with pulse counting equipment 1307c with motor drive circuit 1307a, position sensor 1307b, produce the pulse oscillation circuit 1307d of pulse signal.Position sensor 1307b and pulse counting equipment 1307c detect switch valve 1306b is used at the edge with switch valve 1306a and injection status detection mechanism.In addition, pulse oscillation circuit 1307d, not shown storage device and unshowned CPU are controlling organizations.

Shown in Figure 117 (B)～120 (B), the edge comprises valve bonnet 1361 with switch valve 1306a and is located at valve system 1362 in the valve bonnet 1361.

Be connected with flexible pipe 1305 on valve bonnet 1361, the water inlet 1361a of income flushing water and is just had a not shown water flowing road, edge that main body 1301 is connected with Western-style, discharges the delivery port 1361b of flushing water a.In addition, on valve bonnet 1361, be formed with the 1361c of piston chamber that is communicated with water inlet 1361a and delivery port 1306b.

Valve system 1362 is by being located in the 1361c of piston chamber slidably, close the piston 1362a that is communicated with of water inlet 1361a and delivery port 1361b by taking one's seat in a side, be fixed on the end of piston 1362a coaxially, from the outstanding axle 1362b of valve bonnet 1361, be located between the lower end and valve bonnet 1361 of piston 1362a, piston 1362a loading spring 1362c constituted along an end.

Spray with the internal construction of switch valve 1306b identical with switch valve 1306a with the edge.Cam gear 1306c comprises the edge with cam 1363 with spray with cam 1364, these edges with cam 1363 and injection with cam 1364 coaxial being fixed on the axis of rotation 1365.The edge contacts with cam 1363 with the edge of cam gear 1306c with the front end of the axle 1362b of switch valve 1306a, and injection contacts with cam 1364 with the injection of cam gear 1306c with the front end of the axle 1362b of switch valve 1306b.One end of the axis of rotation 1365 of cam gear 1306c is connected with the stepper motor 1306d shown in Figure 116 with Figure 115 via reduction gearing, and the other end of axis of rotation 1365 is shown in Figure 117 (A)～120 (A), and 1306e is connected with manual handle.

This edge is with switch valve 1306a and spray with switch valve 1306b according to following such action.That is to say that " position discharges water " shown in Figure 117, manual handle 1306e is the state of figure (A).In addition shown in figure (B) because the edge all is half-open position with switch valve 1306a and injection with switch valve 1306b, so that be positioned at underground not shown stopcock and discharge water and become possibility by closing.

In addition, at " origin position " shown in Figure 118, manual handle 1306e is the state of figure (A).In addition shown in figure (B), because the edge all is closed condition with switch valve 1306a and injection with switch valve 1306b, so flushing water a and flushing water b do not discharge.

And then at " the edge flush position " shown in Figure 119, manual handle 1306e is the state of figure (A).As shown in figure (B), the edge is an open mode with switch valve 1306a in addition, discharges flushing water a, and spraying with switch valve 1306b is closed condition, does not discharge flushing water b.

In addition, in " the jet douche position " shown in Figure 120, manual handle 1306e is the state of figure (A).As shown in figure (B), the edge is a closed condition with switch valve 1306a, does not discharge flushing water a in addition, and spraying with switch valve 1306b is closed condition, discharges flushing water b.

In the Western-style flushing of no water tank that constitutes as mentioned above just in the tool, when the user made the flushing of the remote controller 1308 shown in Figure 115 become on-state with button, the edge was controlled by following such pattern by controller 1307 with switch valve 1306b with switch valve 1306a and injection.

When state is " origin position " shown in Figure 118 in the early stage, if the user makes the flushing of remote controller 1308 become on-state with button, then shown in Figure 121, stepper motor 1306d begins just to change, the umber of pulse of pulse counting equipment 1307c counting stepper motor 1306d.If when pulse counting equipment 1307c counts 477 pulses, the signal of position sensor 1307b becomes the H signal from the L signal, confirms that then A-stage is " origin position ".

And the edge is opened with switch valve 1306a, becomes " the edge flush position " shown in Figure 119, when pulse counting equipment 1307c further counts 874 pulses, after the signal of position sensor 1307b becomes the L signal from the H signal, and keeps a period of time.In addition, when pulse counting equipment 1307c continued counting 158 pulses, the signal of position sensor 1307b was after the L signal becomes the H signal, and the edge is closed with switch valve 1306a, and " edge flush position " finishes.

Then, stepper motor 1306d continues just to change, spray and open with switch valve 1306b, become " jet douche position " shown in Figure 120, when pulse counting equipment 1307c continues counting 1272 pulses, the signal of position sensor 1307b is after the H signal becomes the L signal, and stepper motor 1306d reverses before each 185 °, and keeps a period of time.In addition, during-79 pulses of pulse counting equipment 1307c counting, the signal of position sensor 1307b sprays and closes with switch valve 1306b after the L signal becomes the H signal, and finish " jet douche position ".

And then, stepper motor 1306d continues counter-rotating, the edge is opened with switch valve 1306a, become " the edge flush position " shown in Figure 119 once more, when pulse counting equipment 1307c continues counting-1272 pulses, the signal of position sensor 1307b is kept a period of time after the H signal becomes the L signal.In addition, when pulse counting equipment 1307c continued counting-158 pulses, the signal of position sensor 1307b was after the L signal becomes the H signal, and the edge is closed with switch valve 1306a, and " edge flush position " finishes.Thereby, carry out the water shutoff of trap and handle.

Last stepper motor 1306d continues counter-rotating, and when pulse counting equipment 1307c continued counting-874 pulses, the signal of position sensor 1307b became the L signal from the H signal, becomes " origin position " when continuing counting-477 pulses then and stops.So flushing process finishes.

So, in the Western-style flushing tool of no water tank, stepper motor 1306d electricity drives the edge and uses switch valve 1306b with switch valve 1306a with spraying at this.During this time, position sensor 1307b and pulse counting equipment 1307c detect the edge and use switch valve 1306a and spray the state of using switch valve 1306b, and pulse oscillation circuit 1307d etc. are with the pattern control step motor 1306d of needs.

In addition,, in the Western-style flushing tool of no water tank,, can open the edge with half-open position and use switch valve 1306b with spraying at this with switch valve 1306a by with manually operating manual handle 1306e.If, shown in Figure 117, the manager operates manual handle 1306e in order to prevent freezing of winter, make the edge become half-open position with switch valve 1306b with switch valve 1306a and injection, and closing under the state of stopcock, the user opens this stopcock and makes push button become on-state.Same in this case, shown in Figure 121, stepper motor 1306d begins just to change, the umber of pulse of pulse counting equipment 1307b counting stepper motor 1306d.And when pulse counting equipment 1307c counted 238 pulses, the signal of position sensor 1307b became the L signal from the H signal, and when counting 477 pulses, the signal of position sensor 1307b does not become the H signal from the L signal.Therefore, confirm that A-stage is " position discharges water ".

After, under above-mentioned pattern, become " edge flush position ", " jet douche position " and " edge flush position " respectively and turn back to " origin position " afterwards, stepper motor 1306d continues counter-rotating, when pulse counting equipment 1307c continues counting-1192 pulses, the signal of position sensor 1307b becomes the H signal from the L signal, the edge is with switch valve 1306a and spray and to become half-open position with switch valve 1306b, becomes " position discharges water " and stops.So flushing process finishes.

So, pulse oscillation circuit 1307d etc., even, also can make the edge reset to A-stage with switch valve 1306b with switch valve 1306a and injection opening the edge by manual handle 1306e with switch valve 1306a and under spraying with the A-stage of switch valve 1306b after the execution pattern.Therefore, after the user uses, if stopcock is closed,, can reach the effect that prevents that the edge from freezing with switch valve 1306b with switch valve 1306a and injection just then keep the edge with switch valve 1306a with spray with the occluded water in the switch valve 1306b and be discharged to Western-style the discharging water of main body 1301 of having.

Thereby just in the tool, gerentocratic intention in winter and user's use can and be deposited in the Western-style flushing of no water tank of embodiment.
